(a) Mean of fidelities of the matrix completion algorithm (red markers, right axis with 
) and randomly subsampled matrix (black markers, right axis) as a function of the fraction of sampled elements (top axis). The matrix completion algorithm was performed 128 times with each time different random sampling, here the errorbars denote the standard deviation. The blue curve (left axis) represents the singular values 
of the measured data in descending order. (b) The fidelity of the matrix completion algorithm as a function of the fraction of matrix elements at different thresholds 
. Inset: Number of iterations required to run the matrix completion algorithm as a function of the threshold and the fraction of the matrix elements.
